Abstract

A miniature electronic device senses head tilt and informs the user so as to avoid neck strain. The device may inform the user via various audio/visual alarms, and my sound based upon angle, duration, or both. Wireless interfaces to other devices may be provided. The device includes a housing adapted for mounting on a wearer'"'"'s head so as to move in a manner corresponding to front-to-back head movements, an input for receiving information corresponding to a particular forward head tilt angle, and a sensor that detects when a wearer of the device tilt their head at an angle equal to or greater than the particular forward head tilt angle. In particular embodiments the forward head tilt angle is in the range of 5 and 35 degrees, and more particularly approximately or equal to 20 degrees. The sensor may include a gyroscopic sensor, an acceleration sensor or, more preferably, a combination thereof.

Claims

1. A neck posture monitoring device, comprising:

a housing physically coupled to a wearer'"'"'s head such that the housing moves in a manner corresponding to front-to-back head tilt movements made by the wearer;

a memory disposed in the housing for storing information corresponding to a specific, predetermined forward head tilt angle measured relative to a horizontal reference; and

a sensor disposed in the housing that detects the front-to-back head tilt movements made by the wearer; and

electronic circuitry disposed in the housing operative to (a) compare the front-to-back head tilt movements made by the wearer to the stored specific, predetermined forward head tilt angle, and (b) perform a function when the wearer tilts their head at an angle equal to or greater than the stored particular forward head tilt angle.

2. The device of claim 1, wherein the specific, predetermined forward head tilt angle is between 5 and 35 degrees.

3. The device of claim 1, wherein the specific, predetermined forward head tilt angle is substantially 20 degrees.

4. The device of claim 1, wherein the function performed is to activate an alarm disposed in the housing.

5. The device of claim 4, further including a light source for generating a visible alarm.

6. The device of claim 4, further including a transducer for generating an audible alarm.

7. The device of claim 6, wherein the transducer forms part of an earphone or earbud.

8. The device of claim 1, wherein the housing includes one or more fasteners for attachment to eyeglass frames.

9. The device of claim 1, wherein the housing is an on-ear or in-ear housing.

10. The device of claim 1, further including:

a real-time clock for determining date and time; and

a memory for recording a wearer'"'"'s head tilt angle as a function of time.

11. The device of claim 10, further including an alarm that is activated when the wearer meets or exceeds the particular forward head tilt angle a specific number of times over a specific period of time.

12. The device of claim 10, further including an alarm that is activated when the wearer meets or exceeds the specific, predetermined forward head tilt angle for a particular duration of time.

13. The device of claim 1, further including an input for receiving information corresponding to a head neutral position.

14. The device of claim 1, further including an electronic level that operates in conjunction with the sensor to determine when a wearer of the device tilt their head at an angle equal to or greater than the specific, predetermined forward head tilt angle.

15. The device of claim 1, wherein the sensor includes a gyroscopic sensor.

16. The device of claim 1, wherein the sensor includes an acceleration sensor.

17. The device of claim 1, wherein the sensor combines a gyroscopic sensor with an acceleration sensor.

18. The device of claim 1, configured as a self-contained battery operated device.
